Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Notes: As of June 2020 this dataset has been static for several years. Recent versions of NHD High Res may be more detailed than this dataset for some areas, while this dataset may still be more detailed than NHD High Res in other areas. This dataset is considered authoritative as used by CDFW for particular tracking purposes but may not be current or comprehensive for all streams in the state.National Hydrography Dataset (NHD) high resolution NHDFlowline features for California were originally dissolved on common GNIS_ID or StreamLevel* attributes and routed from mouth to headwater in meters. The results are measured polyline features representing entire streams. Routes on these streams are measured upstream, i.e., the measure at the mouth of a stream is zero and at the upstream end the measure matches the total length of the stream feature. Using GIS tools, a user of this dataset can retrieve the distance in meters upstream from the mouth at any point along a stream feature.** CA_Streams_v3 Update Notes: This version includes over 200 stream modifications and additions resulting from requests for updating from CDFW staff and others***. New locator fields from the USGS Watershed Boundary Dataset (WBD) have been added for v3 to enhance user's ability to search for or extract subsets of California Streams by hydrologic area. *See the Source Citation section of this metadata for further information on NHD, WBD, NHDFlowline, GNIS_ID and StreamLevel. **See the Data Quality section of this metadata for further explanation of stream feature development. ***Some current NHD data has not yet been included in CA_Streams. The effort to synchronize CA_Streams with NHD is ongoing.</SPAN></P><P><A href="https://gis.data.ca.gov:443/datasets/CDFW::california-streams-1/about" target="_blank" STYLE="text-decoration:underline;"><SPAN>https://gis.data.ca.gov/datasets/CDFW::california-streams-1/about</SPAN></A></P></DIV></DIV></DIV>

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>NOTE: In 2013, the California Department of Fish and Game (CDFG, DFG) was renamed to California Department of Fish and Widlife (CDFW). This dataset is an update of California lake, reservoir, and pond layers as assembled by the California Department of Fish and Game (DFG). It includes many small and unnamed waterbodies in the High Sierra and California Cascades, some of which are not depicted on USGS 7.5-minute/1:24,000-scale topographic maps. Most data were captured at 1:24,000-scale or better. Waterbodies are represented as single polygons (with islands), with Latitude/Longitude coordinates of waterbody centroids and a unique numeric identifier for each. Waterbody polygons represent shorelines generally at full or near-full levels. A previous version of this dataset did not contain islands. This dataset is considered authoritative as used by CDFW for particular tracking purposes but may not be current or comprehensive for all waterbodies in the state.</SPAN></P><P><SPAN>This dataset represents a combination of 1:24,000-scale or better GIS datasets considered the best currently available. The initial sources come from DFG's fisheries programs, some of which included many Sierra Nevada lakes and ponds not represented on existing USGS maps and/or not known to exist in digitized format elsewhere. Unique ID's in the field DFGLAKEID reflect the LAKE_ID in FPB_Lakes shapefile in about 22,400 cases. Many errors (attribute and spatial) existed in all the contributing datasets, and many (but not all) have been remedied here. Lake name errors were addressed to the greatest extent, spatial representation errors to a lesser extent. USGS National Hydrography Dataset (NHD) High Resolution 'waterbody' polygons were used to replace some existing polygons. It was not used exclusively however, due in part to existing errors within the NHD datasets to date, the lack of completeness for CA and the lack of time on the editors end to incorporate NHD in cases where NHD polygon representation is better than what exists here. It is the intent that NHD polygons will be incorporated more as they get updated.</SPAN></P><P><A href="https://gis.data.ca.gov:443/datasets/CDFW::california-lakes-1/about" STYLE="text-decoration:underline;"><SPAN>https://gis.data.ca.gov/datasets/CDFW::california-lakes-1/about</SPAN></A></P></DIV></DIV></DIV>
